Title: Magnetic properties and phase stability of tetragonal Ce1-xSmxFe9Co2Ti 1:12 phase for permanent magnets

Abstract

In this work, we report the effects of partial substitution of Ce by Sm in CeFe9Co2Ti alloys on their magnetic and structural properties. The alloys were prepared in bulk and melt-spun ribbons. The alloys present the ThMn12 phase in the full range of substitutions, and reach anisotropy fields above 8 T for the best alloy. After heat treatment, melt-spun ribbons show high values of magnetization (>112 A m2/kg), Curie temperatures >370°C and enhanced coercivity. Although the coercivity values obtained are already suitable for permanent magnet applications, they are still low as compared to the anisotropy field (less than 6%). Coercivity is expected to improve by optimizing the microstructure of the best samples.
